Does National require an IDP in Republic of the Congo?

The minimum age to rent is typically 21 (18 in Michigan and New York, as required by state law); renters aged 21-24 pay a "Youthful Surcharge" of approximately $25 per day (varies by location, lower in some states such as $5/day in New York) and may be restricted to certain car classes.

A major credit card (Visa, MasterCard, Amex) in the primary renter's name with sufficient available credit is required; National generally does not accept debit cards, and renters without a ticketed return travel itinerary must provide a hold/deposit typically between $300 and $400 depending on location and vehicle class.

The renter's spouse or domestic partner who meets the same age and licence requirements drives free; other additional authorized drivers cost about $15 per day (typically $5/day in New York), and must be at least 21 with a valid licence. National requires a valid, unexpired full driver's licence held by the renter; for under-25 drivers some locations require the licence to have been held for at least one year, though National does not publish a uniform minimum tenure across all locations.

Vehicles rented in the U.S. or Canada are prohibited from being driven into Mexico; U.S.-Canada cross-border travel is generally permitted but one-way US/Canada drop-offs are limited to participating locations, and rentals originating in certain Mexican cities (e.g. Tijuana, Mexicali, Hermosillo, Monterrey, Saltillo) may cross into the U.S. after purchasing an extension of liability protection (about $10 USD/day).

National states that an International Driving Permit (IDP) is commonly requested in select countries and is generally recommended when travelling abroad; specifically, overseas travelers whose licence uses a non-Roman alphabet may need to present an IDP alongside their home-country licence.

There are no widespread electronic tolls or vignettes; the upgraded Brazzaville-Pointe-Noire (RN1) corridor has some péage barriers paid in cash (CFA francs). Most travel cost is fuel rather than tolls.

Parking in Brazzaville and Pointe-Noire is mostly informal on-street with attendants who expect a small tip; there are no app-based or colour-zone systems. Use guarded hotel or business parking and avoid leaving the car unattended.

Police checkpoints are frequent and may seek on-the-spot cash payments from foreign drivers; ask for an official receipt and keep documents accessible. Common cited offences are missing papers, seatbelt and speeding violations.

Remain at the scene if safe, do not move vehicles when there are injuries, and summon police to file a report for insurance; exchange details with the other driver. If a crowd turns hostile, leave and report at the nearest police/gendarmerie post.
